grep to find the string, awk to slice the file name out of the resulting line, rm -f to force the deletion.

What have you done so far?

Hi TenTenths,

I have created normal logic right now.here is code stuf. i used only one hard coded log file but i want to check all file at this location. which contains some message like "Invalidxxxxx". I want to find 1st how many file contains that message and the want to place some other loc. then clean up .

1 #!/bin/bash
2 #sceipt for checking file names uniquly and checking unique string in each file
3
4 String path="/home/tmadmin/SwapnilT"
5
6 read -p "Enter the path :" $path
7 if [ -e $path ]
8 then
9 echo " path is present / Exits"
10 fi
11
12
13 cat t2.log | grep "invalid*" | sort | uniq
14
15

If you tell me atleast flow will also help me to proceed further coding ???

Regards,
Swapnil Titar

please use [code]here comes your script[/code] to keep formatting
Also
Code:
#instead of:
cat t2.log | grep "invalid*"
#you can use
grep invalid t2.log
Code:
sort | uniq
#is equal to
sort -u
I do not know what is that path good for, but you did not exit if path was present, just message is printed.

In this line:
Code:
cat t2.log | grep "invalid*" | sort | uniq
you don't need to cat in to grep, you should just use
Code:
grep "invalid" *
to check all the files in whatever folder you're in.

So the flow would be:
  1. Enter the path you want to check
  2. Use cd to change to that path
  3. grep "invalid" * to find all the files that contain your search
  4. Pass the results of grep in to awk to slice out the filename
  5. Pass that through uniq and wc -l to find the number of files

Repeat the above but use rm -f to remove the file
